This scatter plot visualizes the relationship between flipper length and body mass for three penguin species, using color-coded circles (yellow for Adelie, green for Gentoo, brown for Chinstrap). The visualization uses D3 v5 APIs including `csv`, `scaleLinear`, `extent`, `axisLeft`, and `axisBottom` to load data from a GitHub-hosted CSV file and render an SVG with custom-styled axes and labels. A CSS rule increases tick label font size, and the plot includes axis titles and a title, though the y-axis label appears misaligned with the plotted variables.
